Intel® Server Boards S4600LH2/T2 TPS Product Architecture Overview
Revision 2.0

NOTE: Care must be taken when selecting heat sinks for the given server board ensuring the screw
layout pattern of the heat sink matches the screw hole pattern of the ILM.
3.1.2 Processor Population Rules
Note: Although the server board does support quad-processor configurations consisting of different
processors that meet the defined criteria below, Intel does not perform validation testing of this
configuration.
For optimal system performance in dual-processor configurations, Intel recommends that
identical processors be installed.
When using a single processor configuration, the processor must be installed into the processor socket
labeled “CPU_1”.
When four processors are installed, the following population rules apply:
 All processors must be of the same processor family.
 All processors must have the same cache size.
 Processors with different speeds can be mixed in a system, given the prior rules are met. If this
condition is detected, all processor speeds are set to the lowest common denominator (highest
common speed) and an error is reported.
 Processor stepping within a common processor family can be mixed as long as it is listed in the
processor specification updates published by Intel Corporation.
3.1.3 Processor Initialization Error Summary
The following table describes mixed processor conditions and recommended actions for all Intel
®
server
boards and Intel server systems designed around the Intel® Xeon® processor E5-4600 product family
and Intel
®
C602 chipset product family architecture. The errors fall into one of the following categories:
 Fatal: If the system can boot, it pauses at a blank screen with the text “Unrecoverable fatal
error found. System will not boot until the error is resolved” and “Press <F2> to enter
setup”, regardless of whether the “Post Error Pause” setup option is enabled or disabled.
When the operator presses the <F2> key on the keyboard, the error message is displayed on the
Error Manager screen, and an error is logged to the System Event Log (SEL) with the POST
Error Code.
The system cannot boot unless the error is resolved. The user needs to replace the faulty part
and restart the system.
For Fatal Errors during processor initialization, the System Status LED will be set to a steady
Amber color, indicating an unrecoverable system failure condition.

 Major: If the “Post Error Pause” setup option is enabled, the system goes directly to the Error
Manager to display the error, and logs the POST Error Code to SEL. Operator intervention is
required to continue booting the system.
Otherwise, if “POST Error Pause” is disabled, the system continues to boot and no prompt is
given for the error, although the Post Error Code is logged to the Error Manager and in a SEL
message.

 Minor: The message is displayed on the screen or on the Error Manager screen, and the POST
Error Code is logged to the SEL. The system continues booting in a degraded state. The user
may want to replace the erroneous unit. The POST Error Pause option setting in the BIOS setup
does not have any effect on this error.
